I am wanting to add on to my existing garage with the roof of the new garage perpindicular to the old garage. The old garage is 24w' x 22' d . My new garage addition will be 24'd x 40' w. Are there any videos or help books on tying the new gable roof to the old roof? The old garage has no overhang on the front and back and the new garage will have a 1' overhang on front and back. Any help is apprecated. I am a novice here.

The company you are buying your trusses from should be able to design this for you.

Why not just remove the roof and trusses off the existing and continue the new trusses onto the old building?

The trusses run in opposite directions. The new addition will be perpendicular to the old addition trusses.

Have a good lumber yard do this for you. If your pitch is the same on the addition as it is on the existing garage, because your addition is wider then existing where it joins the roof will be higher.
Do a google search.

That's what I'm saying, remove the old trusses and replace them with new so they are all running in the same direction.

You just need to stick in the gable. Looks something like the pics below. Hire an experienced framer to help you set the trusses and stick in the gable. You'll learn the right way to do it and keep from getting hurt in the process.

Exept your new roof will be higher than the old one.

Depends on the pitches of the roofs. If he reduces the pitch on the new one he could have it hit under the ridge of the old one, if the old one has a decent pitch to start with, so he doesn't end up with a shallow pitch on the new one. On the pics I posted, the old garage and the new addition were both 28'. The original roof was 7/12, I made the new one 6.5/12. it hit about a foot under the old ridge and worked out well. If he only has a 4 or 5/12 pitch to start with, I wouldn't do it that way.
